Description

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/409,966, filed Sep. 11, 2002, which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates generally to electricity meters, and more particularly to connection interfaces between a circuit board in the meter and electrical elements that are not typically mounted to a circuit board.

BACKGROUND OF THE INVENTION

Meters are used to measure electricity consumption.

To this end, they include sensor devices that connect to and or interact with the utility power lines (sensor equipment) and electronic circuits for performing various calculations using signals generated by the sensor devices.

Sensor devices typically include blades received by meter socket jaws and provide a mechanically and electrically sound connection for handling large currents and voltages. The blades are often connected within the meter by large current carrying conductors. Sensor devices may also include current measurement devices, which can include a sensing coil of some sort. Voltage and current signals are obtained from these devices and provided to a circuit board that may include a/d converters and processing circuits that perform metering calculations.

One source of cost in the meter is the connection between the sensor devices and the electronic circuitry on the circuit board. Sensor devices are too large to be on circuit board. Typically, sensor devices are mounted to the housing below circuit board and then wire connections are provided to the circuit board. Wires are soldered or connected by terminals.

The manufacturing process of wiring sensor devices to a printed circuit board in a meter has drawbacks, including the labor cost of individually connecting wires, as well as potential quality problems, e.g., difficult to run wires and manipulate them in the small interior.

One alternative is provided by Schlumberger. This meter has preformed mounts for sensors, and leaf spring terminals that extend upward form the sensors to the circuit board. Although this meter alleviates the drawbacks of handwiring, it still has drawbacks.

One problem is that a custom mount must be made for each meter form. In particular, different meters often have different blade and sensor configurations. Specifically, various standardized meter forms have been defined that require different wiring and connections between and among the blade and sensor elements. The different meter forms result from the fact that electrical service is provided in different ways to different customers, and the methods of measuring these different types of services changes.

By way of example, FIGS. 1 a, 1 b, 1 c, 1 d, 1 e, 1 f, 1 g and 1 h show different sensor wiring configurations for different meter forms. Each of FIGS. 1 a-1 h shows a representation of a meter base 12 showing the layout of the current blades 14 and a schematic diagram of the connections within the meter base 12, including transformers/coils, potential blades 18 and neutral blades 18 a. In addition, many meter forms include switchable potential links 19 as is known in the art.

FIG. 1 a shows a form 16/15S four wire wire meter configuration, FIG. 1 b shows a form 25S three wire meter configuration, FIG. 1 c shows a form 45S three wire configuration, and FIG. 1 d shows a 12S three wire configuration. The meter forms illustrated in FIGS. 1 a-1 d are known as “self-contained” meter forms because the meter blades connect directly to the power lines. By contrast FIGS. 1 e-1 h illustrated transformer-rated meter forms, which couple to the power lines through a transformer. Specifically, FIG. 1 e shows a form 29S four wire configuration, FIG. 1 f shows a form 36S four wire configuration, FIG. 1 g shows a form 56S three wire configuration, and FIG. 1 h shows a form 9/8S four wire configuration. Such meter forms and their configurations as represented in FIGS. 1 a-1 h are well known in the art.

Because different meter forms require different blade and sensor wiring connections, the use of customized base mounts requires that different base mounts be created for each form, which is not always a cost effective solution because of the tooling costs and logistical costs of manufacturing and maintaining several custom designs.

Accordingly, there is a need for a method of reducing the amount of labor involved in wiring sensor devices of electricity meters to the smaller components on the circuit boards of utility meters that does not require custom molds and manufacturing techniques for each different meter form.

SUMMARY OF THE INVENTION

The present invention addresses the above described need, as well as others, by providing a connector buss that includes a conductive form from which a plurality of connector configurations may be readily formed. In particular, the conductive form has a series of contact connectors for receiving meter sensor devices, and a network of conductors in between. By selectively introducing discontinuities in particular ones of the conductors, different meter form connections may be created.

A first embodiment of the invention is a configurable buss element for an electricity meter that includes a conductive piece of metal formed into a series of contact connectors and a network of elongate conductors extending between and among the series of contact connectors. Each of the plurality of contact connectors is configured to contact a circuit element of an electricity meter. The network of elongate conductors is operable to provide connectivity between the contact connectors and select portions of the conductive piece of metal in one of a plurality of connectivity configurations, each of the connectivity configurations corresponding to an electricity meter configuration, the select one of the plurality of connectivity configurations defined by a predetermined set of discontinuities introduced in the network of elongate conductors.

The above described features and advantages, as well as others, will become more readily apparent to those of ordinary skill in the art by reference to following detailed description and accompanying drawings.

DETAILED DESCRIPTION

FIG. 2 shows a schematic block diagram of a meter 100 that incorporates aspects of the present invention. The meter 100 is configured to measure energy delivered to a load via power lines 110. The meter 100 includes sensor devices 112, a configurable interface 114, and an electronic measurement circuit 116. The sensor devices 112 connect to power lines 110 and generate signals representative of the voltage and current waveforms on the power lines 110. To this end, the sensor devices 112 include one or more current blades, such as the current blades 14 of FIGS. 1 a-1 h. The sensor devices 112 may further include voltage and current sensing and/or scaling devices as is well known in the art.

The electronic measurement circuit 116 is a circuit disposed on one or more supports, such as one or more circuit boards (see e.g. the circuit board 154 of FIG. 3). The electronic measurement circuit 116 is a circuit configured to determine a measurement of the amount of energy being consumed by the load using the signals representative of the current and voltage waveform received from the sensor devices. To this end, the electronic measurement circuit 116 is connected to receive a voltage measurement signal for one or more phase of the power line received from the sensor devices 112, and is further connected to receive a current measurement signal for one or more phases of the power line received from the sensor devices 112.

The configurable interface 114 provides an electrical connection between one or more of the sensor devices and the electronic measurement circuit 116. The configurable interface 116 has a standard interface to the electronic measurement circuit 116, a standard interface to the sensor devices 112, and provides a configurable set of connections between the standard sensor interface and the standard measurement circuit interface. In the embodiment described herein, the configurable interface 114 primarily provides voltage or potential measurement connections between the sensor devices 112 and the electronic measurement circuit 116. Current measurement connections are provided independent of the configurable interface 114, as illustrated by line 114 a of FIG. 2. However, it will be appreciated that current measurement connections may also made through the configurable interface 114 if desired.

An exemplary embodiment of the meter 100 is shown in FIG. 3. In particular, FIG. 3 shows a partial exploded perspective view of an exemplary meter 100 that incorporates aspects of the invention. Like elements of FIGS. 2 and 3 employ like reference numbers.

The meter 100 includes an exemplary housing that includes a base support 120, an intermediate support 122 and a cover support 124. The base support 120 is configured to mate with a standard ANSI meter socket, not shown, and is operably to mechanically couple to the intermediate support 122 and the cover support 124. The base support 120, the ANSI meter socket, the intermediate support 122 and the cover support 124 are aligned in a first direction, referred to herein as the axial direction.

The base support 120 may suitably be a molded structure generally comprising a platform 126 and a set of supports 128. The platform 126 generally forms the bottom wall of the meter, and generally extends in one or more planes that are normal to the axial direction. A number of features are molded into the platform 126 that facilitate support of various elements of the meter 100. The nature and extent of these features will necessarily vary from meter to meter and would be readily apparent to those of ordinary skill in the art. Nevertheless, at least some of the features are openings 130 through which the

current blades

14 a, 14 a′, 14 b, 14 b′, 14 c and 14 c′ may extend. The supports 128 extend axially downward from the platform 126.

The base support 120 has an outline shape which refers to the general shape the base support in the plane normal to the axial direction. In the exemplary embodiment described herein, the outline shape is generally circular. However, it will be appreciated that the outline shape of the base support 120 may be rectangular or some other shape. In ANSI meters, however, the outline shape will typically be circular.

The intermediate support 122 is an enclosure or cover that fits over the platform 126 of the base support 120. The intermediate support 122 includes a top shelf 131 and a cylindrical sidewall 132 extending axially downward from the top shelf 131. The sidewall 132 and top shelf 131 define a cavity 134 between the platform 126 and the top shelf 131.

The configurable interface 114 is disposed within the cavity 134, and is supported by or on the platform 126. The configurable interface 114 includes a conductive piece of metal 136 attached to a support member 138. In the embodiment described herein, the support member 138 is constructed of molded plastic, preferably polypropylene. The support member 138 is further preferably overmolded onto the conductive piece of metal 136 to partially encapsulate the conductive piece of metal 136.

The conductive piece of metal 136 is formed to define a number of contact connectors (

connectors

140 a, 140 b, and 140 c are shown in FIG. 3) and a network of elongate connectors 142. Each of the contact connectors is configured to receive a portion of a sensor blade, such as a current or voltage blade of a utility meter. In the exemplary embodiment of FIG. 3, the

connectors

140 a, 140 b, 140 c are located such that they will receive the current blades of most self-contained meter forms, such as those shown in FIGS. 1 a-1 d. The network elongate connectors 142 is arranged such that selective portions may be punched in any of a plurality of connector configurations that correspond to a particular meter form.

In particular, as discussed above, the conductive piece of metal 136 has uniform contact connectors (e.g. 140 a, 140 b, 140 c) that can receive current blades arranged for use in a number of meter forms. The conductive piece of metal 136 furthermore has uniform circuit board contact outputs (e.g. contact output 144 c of FIG. 5) that are electrically connected to the circuit board 154 discussed further below. For each meter form, different connections must be made between the circuit board contact outputs, current blades and even transformer or switch connections. The circuit board contact outputs (see outputs 144 a-144 d of FIGS. 4 and 5) allow voltage or potential measurements from the sensor blades and/or devices to be provided to the measurement circuit 116 on the circuit board 154.

In the embodiment of FIG. 3, the conductive piece of metal 136 (see also FIG. 5) also includes a number of screw terminals 158 a-158 h (only 158 f and 158 h shown in FIG. 3). These screw terminals 158 a-158 h allow for connection of neutral blades 18 a, potential link switches 19, which may or may not be used depending on the meter form.

For example, FIGS. 1 a-1 d show various meter forms that generally employ similar (and compatible) current blade layouts, but have different connection requirements. For example, in FIG. 1 a, the 16S meter generally defines that potential measurements should be taken from the outputs of the potential link switches 19 as well as the neutral blade 18 a, while in FIG. 1, the 45S meter form generally defines that potential measurements should be taken from potential blades 18 and the neutral blade 18 a. In FIG. 1 b, the 25S meter form defines that potential measurements should be taken directly from the current blades 14 and the neutral blade 18 a, while in FIG. 1 d, the 12S meter form defines that potential measurements should be taken from one current blade 14, one potential link switch 19, and one of three possible neutral blade positions 18 a.

The conductive piece of metal 136 is designed such that the network of elongate conductors 142 may be readily configured to provided the connection requirements for each of those meter forms. To configure the conductive piece of metal 136 for a particular meter form, select portions of the metal are cut out or punched out. The select punch out configuration connects predefined receptacles for current blades 14, potential blades 18, neutral blades 18 a and potential links 19 with predefined output contacts (e.g. 144 a-d of FIG. 4).

Preferably, the conductive piece of metal 136 is a phosphor bronze stamping. It will be appreciated that one or more of the conductors of the network of elongate connectors 142 may be included primarily to ensure that the conductive piece of metal 136 may be formed and manipulated as a single piece. In other words, some of the elongate conductors may never be intended to provide an electrical connection, but function as a bridge section that holds the conductive piece of metal 136 together as a unit. Portions of such elongate conductors are then punched out (along with other conductors not necessary for the meter form) after the support member 138 is secured to (e.g. overmolded onto) the conductive piece of metal 136.

Further detail regarding the specific embodiment of the conductive piece of metal 136 and the support member 138 of FIG. 3 are provided below in connection with FIGS. 4 and 5. An alternative embodiment of a conductive piece of metal and support member suitable for various forms of transformer-rated meters are provided below in connection with FIGS. 6 and 7.

Referring again to the general assembly of the meter 100 of FIG. 3, the support member 138 includes a number of openings 146 a-146 d that provide access to the circuit board contact outputs 144 a-144 d, respectively (

outputs

144 a, 144 b, and 144 d shown in FIG. 4 only). Extending generally axially upward from each of the openings 146 a-146 d is a corresponding leaf spring conductor 148 a-148 d. Each leaf spring conductor 148 a-148 d provides an electrical connection between the circuit board contact outputs 144 a-144 d of the conductive piece of metal 136 to analog inputs of the circuit board 154.

In the embodiment of FIG. 3, the meter 100 includes three pairs of meter blades, 14 a and 14 a′, 14 b and 14 b′, 14 c and 14 c′. Each pair is connected by a conductive bar referred to as a current coil. Thus,

meter blade pair

14 a, 14 a′ is connected by the current coil 150 a,

meter blade pair

14 b, 14 b′ is connected by the current coil 150 b, and the

meter blade pair

14 c, 14 c′ is connected by the current coil 150 c. In many embodiments, such as the one illustrated in FIG. 3, each meter blade pair and its corresponding current coil is formed as a single metal bar. Current blades, their positioning within the meter, and suitable types of construction are well known in the art.

In the embodiment described herein, three

current transformers

152 a, 152 b, and 152 c are in a current sensing relationship with the

current coils

150 a, 150 b and 150 c, respectively. Specifically, the current transformer 152 a is in the form of a toroid, and includes a center opening through which a portion of the current coil 150 a and or current blade 14 a passes. The

current transformers

152 b, 152 c are configured in an analogous manner.

In the assembled meter 100, the

current coils

150 a, 150 b and 150 c, and the

current transformers

152 a, 152 b and 150 c all reside within the cavity 134 between the top plate 131 of the intermediate support 122 and the configurable interface 114. However, the

blades

14 a, 14 a′, 14 b, 14 b′, 14 c and 14 c′ all extend axially through the configurable interface 114 and through the platform 126 to the exterior of the meter 100. The

blades

14 a, 14 a′, 14 b, 14 b′, 14 c and 14 c′ extend axially downward from the platform 126 so that they may be received by standard meter socket, not shown, but which is well known in the art.

When the meter 100 in installed in a suitable meter socket, the

blades

14 a, 14 a′ are positioned to be connected in the path of the phase A power line, the

blades

14 b, 14 b′ are positioned to be connected in the path of the phase B power line, and the

blades

14 c, 14 c′ are positioned to be connected in the path of the phase C power line. As a consequence, the phase A current flows through, and the phase A voltage is present on, the

current blades

14 a, 14 a′ and the current coil 150 a. Similarly, the phase B current flows through, and the phase B voltage is present on, the

current blades

14 b, 14 b′ and the current coil 150 b, and the phase C current flows through, and the phase C voltage is present on, the

current blades

14 c, 14 c′ and the current coil 150 c.

It is noted that select of the current blades (e.g 14 a) pass through and make electrical contact with select contact connectors (e.g. 140 a) of the configurable interface 114. In the exemplary embodiment of FIG. 3, the

current blades

14 a, 14 b, and 14 c pass through and make contact with, respectively,

contact connectors

140 a, 140 b, and 140 c. The current blade 14 b′ also passes through another contact connector 140 d, not shown in FIG. 3 (see FIG. 4). The particular current blade and current transformer configuration of FIG. 3 corresponds to a 16/15S meter form, such as illustrated in FIG. 1 a.

Referring again to the intermediate support 122, the top shelf 131 supports a printed circuit board 154 on which at least a portion of the electronic measurement circuit 116 resides. The top shelf 131 includes

openings

156 a, 156 b and 156 c through which the

leaf spring connectors

148 a, 148 b, and 148 c pass, thereby allowing contact of the

leaf spring connectors

148 a, 148 b, and 148 c with select predetermined input locations on the printed circuit board 155. The leaf spring connector 148 d passes through a similar opening in the top shelf 131, not visible in FIG. 3. Additional openings, not shown, may be provided to allow the leads from the

current transformers

152 a, 152 b and 152 c to pass to the circuit board 154.

As discussed above, the embodiment of the meter 100 shown in FIG. 3 is shown as a 16S meter form, which corresponds to the FIG. 1 a standard wiring diagram. In a 16S meter form, voltage measurements are taken from each phase voltage with respect to a neutral. Specific to the meter form (see FIG. 1 a), the voltage measurements are typically taken at the output of the potential link as is known in the art. To this end, in the meter 100 of FIG. 3, the

contact connectors

140 a, 140 b, and 140 c obtain the phase A, B and C voltages, respectively. The conductive piece of metal 136, which will have been previously punched out in a predetermined pattern defined for a 16S meter form, will provide the phase A voltage to the leaf spring connector 148 a through the output contact 144 a (see FIG. 4). The conductive piece of metal 136 will similarly provide the phase B voltage to the leaf spring connector 148 b through the output contact 144 b (see FIG. 4), and provide the phase C voltage to the leaf spring connector 148 c through the output contact 144 c. In a 16S meter form, each of the above connections further occurs through a potential link, not shown, connected to two of the screw terminals 158 b-158 g.

As is known in the art, the meter 100 includes a neutral potential blade (see representative blade 18 a of FIG. 1 a). Although not shown in FIG. 3, such a blade would typically be secured to the platform 126 in an industry standard location, and extends axially downward through the platform 126 to the exterior of the meter 100. The neutral blade is connected to one of the screw terminals 158 a-158 h, and specifically screw terminal 158 g in the 16S meter form. Alternatively, a wire lead (or other type of connector) would be provided to a predetermined position on the conductive piece of metal 136. In any event, the neutral blade is electrically connected to the leaf spring connector 148 d.

Thus, because of the configuration of the conductive piece of metal 136, the

leaf spring connectors

148 a, 148 b, 148 c and 148 d provide to the measurement circuit 116 on the circuit board 154 the phase A, B, and C potentials. The measurement circuit 116 then uses this information along with phase A, B and C current information provided by the

current transformers

152 a, 152 b and 152 c to perform various energy-related calculations.

The cover support 124 is a generally cylindrical body that covers over the intermediate support 122 and the interior 134. In an exemplary embodiment, the cover support 124 supports an LCD display 125. However, it will be appreciated that a display may alternatively be supported on the intermediate support 124, or by still another support member, not shown.

FIGS. 4 and 5 show in greater detail the configurable interface 114 of FIG. 3. In general, the configurable interface 114 is suitable for self-contained meter forms, and specifically, forms 1 a, 1 b, 1 c, and 1 d. The conductive piece of metal 136 includes a set of

contact connectors

140 a, 140 b, 140 c and 140 d, each having a center opening generally configured to receive a standard current or potential blade. Each of

contact connectors

140 a, 140 b, 140 c and 140 d include inward extensions within the center opening that engage an inserted sensor blade. The inward extensions deform slightly when the blade is inserted, and tend to urge the blade toward the other inward extensions located on the opposite side of the center opening.

The contact connector 140 a receives the phase A current blade in each self-contained meter form of FIGS. 1 a-1 d. The contact connector 140 b receives the phase B current blade in the 16S form, and receives a phase A high potential blade in the 45S form. The contact connector 140 c receives the phase C meter form in all forms in FIGS. 1 a-1 d. and the contact connector 140 d receives the phase B current coil in the 16S form, and receives the phase A low potential blade in the 45S form.

The output contacts 144 a-144 d represent slightly width extensions on the network of elongate conductors 142. The output contact 144 a provides a phase A voltage output to the circuit board 154 in forms 16S, 25S and 12S. The output contact 144 a provides phase A high potential voltage output to the circuit board in form 45S. The output contact 144 b provides the phase B voltage output to the circuit board 154 in form 16S, and provides the phase A low potential voltage output to the circuit board 154 in form 45S. The output contact 144 c provides a phase C voltage output in all self-contained forms of FIGS. 1 a-1 d. The output contact 144 d provides a neutral connection in all forms of FIGS. 1 a-1 d.

The screw terminal 158 a connects to a neutral blade in forms 25S and 12S. The

screw terminals

158 b, 158 c connect to a potential link in the 16S form, as do the

screw terminals

158 d, 158 e. The

screw terminals

158 f, 158 g connect to a potential link in meter forms 16S and 12S. The screw terminal 158 g connects to a neutral blade in forms 16S, 45S and 12S. The screw terminal 158 h connects to a phase C potential blade in form 45S.

The network of elongate conductors 142 are configured as shown, or in a similar manner, to connect the various elements described above. Portions of the network of elongate conductors 142 may be selectively cut or removed such that the remaining connections provide the connectivity defined for one of the self-contained meter forms. Those of ordinary skill in the art may readily determine how to cut the elongate conductors 142. FIG. 4 shows a number of cut-out blanks 162 formed in the support 138. The location of these cut-out blanks 162 provides an indication of possible locations at which the network of conductors 142 may be cut. The cut-out blanks 162 are preferably of lesser thickness than other portions of the support 138 in order to facilitate punching out of those portions.

Referring again to the network of conductors 142, the cut-outs or punch outs should be of sufficient length to prevent phase to phase arcing across the space formed by the cut-out. By way of example, the cut-outs should be at least four tenths of an inch long. The cut-out blanks 162 should have at least this length to facilitate a proper length punch out. It is noted that adjacent (i.e. parallel) conductors of the network 142 may be closer than four tenths if the support 138 is molded around the conductive piece of metal 136. In such a case (or if the support 138 is potted around the metal 136), the support acts as a guard against phase to phase arcing.

By way of example, to form a 16S meter, punches should be made through the network of conductors 142 (and the cutout blanks 162) at the

cutout blanks

162 a, 162 b, 162 c, 162 d, 162 l, 162 j, 162 k, 162 g and 162 h, at a minimum.

Using the above described configuration as an example, the concept may be applied to the transformer-rated forms of FIGS. 1 e-1 h using the configurable interface of FIGS. 6 and 7. In FIG. 7, the contact connectors 240 a-240 g receive potential blades and optionally KYZ blades, as illustrated in FIGS. 1 e-1 h. Cutouts 262may be used to ensure that the proper KYZ blades are connected to KYZ outputs 248 a-c, and that the potential blades are connected to the corresponding outputs 144 a-144 d.

Because self-contained meters generally only obtain voltage measurements from potential blades (and not a combination of current blades, potential blades, and potential links), the implementation of the cutouts in FIG. 1 e-1 f is more readily discerned from inspection of FIGS. 1 e-1 f, 6 and 7. Accordingly, further description is not necessary.

It will be appreciated that the exact configuration of the network of connectors 142 in either embodiment may take a nearly infinite number of forms and accomplish the same result. Accordingly, broad aspects of the invention do not contemplate the exact layout of the network of conductors 142, so long as they may be configured to connect the other elements of the conductive piece of metal and may be cut out in patterns to establish connection configurations between sensor blades and output contacts to a circuit board.
